Pope Honorius IV

Pope Honorius IV (1210-3 April 1287), born Giacomo Savelli, was Pope from 2 April 1285 to 3 April 1287, succeeding Pope Martin IV and preceding Pope Nicholas IV.

Biography
Giacomo Savelli was born in 1210 to the House of Savelli in Rome, and in 1261 Pope Urban VI appointed him Cardinal-Deacon of Santa Maria in Cosmedin, a title which he held until 1285. He was consecrated as Pope on 2 April 1285, and his rule was filled with troubles surrounding the War of the Sicilian Vespers. Honorius excommunicated Jaume II of Aragon, but Jaume did not concern himself with his excommunication; he sent a fleet to raze the city of Astura, which he destroyed. Honorius supported the future Charles II of Sicily's claims, but he eventually had to agree to King Edward I of England's mediation between Alfonso III of Aragon and Charles. He died in 1287.
